"Dinosaurs of the Perkiomen Valley"

Presenter: John C. Kraft, Ph.D. 225-180 million years ago, some of our favorite "movie stars" were on the scene. Absent were well-kept lawns and leafy green trees. Unheard of were snowflakes or sleet. Dr. Kraft will share his knowledge about this time period through a slide presentation, hands-on exhibit of area rocks and minerals, and a few tracks of...Perkiomen Valley dinosaurs!
